Hi, I've searched every catalog and website for "Fast Blue" (Diamidino compound 253/50), widely used for neuronal retrograde tracing. One recent paper using this compound is:
Porreroa et al "Mapping of fluorescent protein-expressing neurons and axon pathways in adult and developing Thy1-eYFP-H transgenic mice", Brain Research, 1345, 59-72 where the authors as many before them cite "Dr. Illing GmbH & Co. KG, Groβ-Umstadt, Germany" as the origin. I have been unable to locate this particular vendor. I've written the authors and am waiting for an answer. In the meanwhile, can anyone on this list help?
